EDIT 2021-12-04 14:59 +0200: Added the text of the presentation.

On Saturday 2021-12-04 at 15:00 +0300 I did a live session where I talked about the GNU Emacs packages I maintain and generally what I have been up to over the past few weeks. The stream has been recorded and can be accessed at any time.

The video is almost 2 hours and 30 minutes long. Most of it was dedicated to the live chat where we talked about a number of issues, including Emacs start-up time, philosophy, being open-minded, and so on.

The text of the presentation:

#+TITLE: Live: Status update on my Emacs work
#+AUTHOR: Protesilaos Stavrou (https://protesilaos.com)
#+DATE: 2021-12-04

Hello everyone!  My name is Protesilaos also known as "Prot".  Today I
will provide a status update on my packages for Emacs and then talk a
bit about EmacsConf 2021.

I posted a notice for this stream only a few hours ago, so I don't
expect anyone to show up.  No worries though.  The video will be
recorded.

If anyone does appear in the chat, feel welcome to send me any questions
you may have and I will answer them right away.

* LIN and upstream patch for hl-line.el

+ Official manual: https://protesilaos.com/emacs/lin
+ Git repo: https://gitlab.com/protesilaos/lin

I recently published a package that lets you remap the styling of the
"line highlight" face (~hl-line-face~) for any buffer you want.  I have
posted about it on my blog, but let me quickly show you what I mean
here. [live demo...]

Basically =lin-mode= lets us use the best design for each context.  No
need to make awkward compromises.  In line-oriented buffers where
selection is the primary mode of interaction, we use a more intense
background.  For all other cases we can afford a more subtle line
highlight.

I tried to submit the package to GNU ELPA but was instead asked to turn
it into a patch for the built-in =hl-line.el=.  I did that but the
documentation I provided is a bit technical so it must be reworded in
the interest of simplicity.  I will try to revisit this issue next week.

Even if we get the patch upstream, I think Lin is still worth having.
That is because the upstream method is supposed to provide only the
relevant points of entry and interested major modes will have to start
using them.  Whereas a package "just works" and gives the user the power
to implement it wherever they want right now.

Anyway, thanks to people who have contributed to Lin:

* Minibuffer and Completions in Tandem (MCT)

+ Package name (GNU ELPA): =mct=
+ Official manual: https://protesilaos.com/emacs/mct
+ Change log: https://protesilaos.com/emacs/mct-changelog
+ Git repo: https://gitlab.com/protesilaos/mct

This is a thin layer of interactivity over the default completion
framework.  It is meant to basically make it easier to use the standard
=*Completions*= buffer.  I announced this package via a video demo on
2021-10-22.  Since then lots of work has gone into making it work with
the two grid views that Emacs provides for the Completions' buffer, in
addition to the one I prefer the most: the =one-column= view of Emacs 28
or higher.  In general, MCT now does the right thing in all scenaria
that involve the minibuffer and the =*Completions*=.  If anything, it
shows that Emacs has a lot of untapped potential for its out-of-the-box
experience.

You have seen me using MCT and my dotemacs-specific predecessor for
almost a year now.  Again, here is a very basic demonstration. [live
demo...]

MCT follows a minimalist design philosophy.  So it combines nicely with
other relevant tools, like Daniel Mendler's =consult= package and Omar
Antolín Camarena's =embark=.  Again, I have covered those and others in
previous videos.

The manual of MCT includes references to more extensions like
=consult-dir= by Karthik Chikmagalur, =consult-notmuch= by José Antonio
Ortega Ruiz, and =all-the-icons-completion= by Itai Y. Efrat.

Right now MCT does not work outside the minibuffer.  So you cannot use
it for tab-completion inside an ordinary buffer, in Eshell, etc., even
though Emacs does use the =*Completions*= buffer for such a task.  This
case is known as ~completion-in-region~ and does not activate the
minibuffer.

There are plans to make MCT optionally work everywhere.  Daniel Mendler,
who is also the author of the excellent =corfu= package, is helping me in
this endeavour (=corfu= does in-buffer completion with a pop-up at where
the cursor is).

A quick joke: a user noted that /Minibuffer and Completions in Tandem/
will have to be renamed if it ever supports in-buffer completion.  I
explained the technical reason why renaming is not an option, but also
observed that MCT stands for /Minibuffer Confines Transcended/.  So there
you have it!

The project is new, but I wish to thank everyone who has contributed
with code and/or ideas: Case Duckworth, Daniel Mendler, James Norman
Vladimir Cash, Jonathan Irving, José Antonio Ortega Ruiz, Kostadin
Ninev, Manuel Uberti, Philip Kaludercic, Theodor Thornhill.

* Modus themes version 2.0.0

+ Package name (GNU ELPA): =modus-themes=
+ Official manual: https://protesilaos.com/emacs/modus-themes
+ Change log: https://protesilaos.com/emacs/modus-themes-changelog
+ Sample pictures: https://protesilaos.com/emacs/modus-themes-pictures
+ Git repo: https://gitlab.com/protesilaos/modus-themes

You are most likely familiar with my =modus-themes=.  They are designed in
conformity with the highest accessibility standard for legibility.  And
they also work well for users with red-green colour deficiency.  The
themes (=modus-operandi= and =modus-vivendi=) are built into Emacs version
28, which will soon be released as the new stable version of Emacs.
They are, of course, in Emacs 29 as well as part of the emacs.git source
code.

I have been making progress towards version 2.0.0.  This is a major
undertaking to review all the packages or face groups that we cover and
also to refine the themes' code.  I have removed support for some
packages that are either obsolete or do not require any further
intervention.  If you think I made a mistake, please let me know and I
will fix it.

There is an issue in my git repo which tracks my progress.  The
underlying data is in Org notation, so I will share the file separately
tgoether with the release notes.  In the meantime you can check more
here: https://gitlab.com/protesilaos/modus-themes/-/issues/259.

There are two changes to user options that are worth noting at this
point:

+ The new ~modus-themes-deuteranopia~ toggle consolidates and supersedes
  all the stylistic choices that existed before for red/blue colour
  coding instead of red/green.  Now users can just set that option to
  non-nil (=t=) and every relevant context will adapt accordingly, like
  diffs, Org TODO and DONE keywords, the Org habit graph in the agenda,
  and so on.

+ The ~modus-themes-diffs~ no longer support a foreground-only style.
  After months of testing, I have concluded that it is not good enough
  for our purposes even though the colours did pass the accessibility
  standard of a minimum contrast ratio in relative luminance of 7:1.
  Put simply, I think the result was not up to the aesthetic standard of
  the rest of the themes.  The manual contains a new section with
  detailed code on how users can implement such a foreground-only style
  in their local setup.

Speaking of aesthetics, this is an aspect of the development that I have
not mentioned enough, so one might not realise some of the more nuanced
insights that go into this project.  There was this case the other day
where Damien Cassou correctly observed a stylistic inconsistency when
using ~hl-line-mode~ in Magit's Git commit buffers.  In that context, the
first line should not exceed 50 characters in length.  Any excess
character would be marked with a yellow background, but hl-line
overrides backgrounds, so the distinction was not clear enough.  I
explained how we could make the excess characters yellow and, to ensure
the best results, colourise the valid text of the summary in blue.  Why
did I make that suggestion?  Because I know that blue and yellow are
complementary colours (for our domain in technology), meaning that they
contrast well when put side-by-side.

At any rate, version 2.0.0 will be released before the end of this year
and, as always, will be synced with emacs.git and all relevant package
archives.

As always, thanks to everyone who has contributed code and/or ideas.
The list of names is too long to include it here.  There is a section in
the manual titled "Acknowledgements" where you can find everyone.

Unlike text, icons occupy a larger surface area and thus have a lower

I am caught between two minds here: on the one hand, it is easier for
new users to tweak standalone user options, yet on the other we are
using a more restricted setup than we could.  Perhaps it would be better
for ~modus-themes-headings~ to accept a number value as part of the
heading's properties.

,*** TODO Remove modus-themes-scale-small

It is not useful in general.  It is only used in the Org agenda and it
breaks the otherwise neat alignment (because it is contingent on the
size of the font, rather than being done pixelwise)...  The idea of
smaller text in the agenda is appealing, but not if it break things.

,*** TODO Decide on modus-themes-scale-title

If we remove/refactor the ~modus-themes-scale-N~ then what must become of
this?  It is used for titles in Org documents as well as the Org agenda
structure.

,** TODO [#C] Formalise guidelines for package support

Going forward, I want us to be more opinionated about which packages we
support.  Otherwise the scope of the themes is practically infinite.

This is a /tentative/ list of scenaria, with the understanding that we are
never going to subject ourselves to a mechanistic process and shall
always exercise judgement:

+ The package has an established user base and/or clear niche and/or is
  actively maintained.  If a package re-invents an existing feature in a
  way that is not clearly better, then we exercise a "wait-and-see"
  approach (we do not need to support a new package from day one).

+ The package is generally useful and is not tied to someone's personal
  setup.  Example of packages that are disqualified: =prot-diff.el= from
  [[https://gitlab.com/protesilaos/dotfiles][my dotfiles]].

+ The package can be used without registering for some external service.
  For example, I cannot maintain =sx= because I do not use the
  stackexchange service.  In such cases, users must actively help with
  the design.

+ The colours that the package uses are not consistent with the
  technical objectives of the themes (accessibility, deuteranopia
  support where relevant) OR in case where it inherits from font-lock
  faces, the result does not look good in context and/or consistent with
  the rest of the theme.  For example, a package that inherits the
  ~region~ face when what it really wanted was ~match~ or ~highlight~.

+ If the package hardcodes colour values like red or green instead of
  inheriting from the ~error~ or ~success~ faces, we first try to contact
  the maintainer to provide a patch that works with all themes.  Same
  principle for when it inherits from base faces but does it in a
  sub-optimal way (like the above example with ~region~ and ~match~ or
  ~highlight~).  A small patch upstream is for cases where we would have
  done exactly that at the theme level.  Contributing to packages is
  better for the ecosystem.

+ There are several packages/faces that hardcode colour values which are
  taken from the Modus themes or are consistent with our objectives.  We
  normally do not need to explicitly style those.  If, however, there is
  something we should do, such as to make the faces conditional on a
  customisation option, then we must style them (provided the package is
  useful, has a user-base, etc.).  Doing so while informing the package
  maintainer is also a good idea.

  Everything should now be subject to a single toggle:
  modus-themes-deuteranopia.  The modus-themes-success-deuteranopia is
  thus superseded, while the individual deuteranopia-friendly styles for
  diffs and the Org agenda's habit graph are altogether removed (there
  is no clean way to notify the user of their deprecation---apologies
  for the inconvenience!).

Note [[https://gitlab.com/protesilaos/modus-themes/-/issues/258][issue 258]] about the potential of using colour space adjustments to
cover all types of colour deficiency.  I think the consolidation into a
single boolean does not contradict that notion, but we will see.

  There is a new section in the manual for those who want to restore
  that style.  I have been meaning to remove it for a long time, because
  it is not up to the established standard of the themes, but there was
  no good opportunity to do so.  Now that we are approaching version
  2.0.0 of the themes, it is right to make such backward-incompatible
  changes.

* EmacsConf 2021

Last week was the annual Emacs conference.  There were lots of
interesting talks: https://emacsconf.org/2021/schedule/.  You can follow
that link to review the schedule and to download any material you want.

I also made a presentation about how Emacs made me appreciate software
freedom.  Again, check the link for a download.  Or wait until I post
the video on my website and this channel.

Right now I just want to answer some questions from the event that I
only noticed today---it was not my intention to ignore them:

#+begin_quote
Q1: (Unrelated, feel free not to answer): Is there an Emacs or GNU/FSF
group in Cyprus? I know it's a politically motivated country, with a
strong student-base, so I'm interested whether the Emacs circles and
political circles have any overlap.
#+end_quote

A1: I don't know of such a group.  Maybe it exists but I live far away
from the city centres so I am not aware of anyone interested in those
issues.  When I was a university student here, there was no overlap
between politics and software freedom.  I was involved in
extracurricular activities but never heard anything related to
GNU/Linux, let alone Emacs.  Though to be fair, I was not tech-savvy
during those years.  I only got into computers at around 2012 and into
free software from mid-2016.

#+begin_quote
Q2: What do you think is the most effecitve way to demonstrate the value
of software freedom to non-techincal people? For a person who can't
program (or doesn't want to learn) the freedom seems less immediate.
#+end_quote

A2: I think the most effective way is to let people use the software.
Yes, the freedom is less obvious because you are not making things
happen from scratch.  But you do not have to.  The whole point of
software freedom, the reason we have a movement and communities, is to
understand and experience liberty in its full intersubjective scope.
Simply put, everyone experiences freedom by virtue of using free
software: they do not fear that some mega-corporation will terminate
their subscription, violate their privacy, and so on.  In the future I
will elaborate on intersubjectivity as pertains to this issue, but
hopefully this gives you an idea.

#+begin_quote
Q3: your quote "emacs makes emergent workflow's possible" reminds me
very much of the previous talk (Emacs as Design Pattern Learning). Can
you share/reflect how you go about making/designing your personal
workflows?
#+end_quote

A3: Just to clarify for others that you refer to the talk of Greta Goetz
(do watch it, by the way---there are many others, but if I mention some
I might unintentionally forget someone).  To your point: I like to use
packages that have a clear scope and follow good coding standards.
Simply put, this means that I prefer minimalist implementations that
lend themselves to composability.  I have explained before, both at
length and in depth, why I think Emacs is consistent with the Unix
philosophy; a philosophy that I consider interesting and fecund when
treated as a philosophy instead of a dogma or a mere historical
artefact.  When you have such sharp tools, you can easily combine them
when the need arises.  And because of their clean implementation, you
can make interventions where necessary to provide whatever missing glue
code.  Plus everything I covered in my EmacsConf 2021 presentation about
the introspecticability of Emacs and its other virtues.

* Joint video with David Wilson (System Crafters)

This is an issue that was brought up during EmacsConf and I also noticed
it in David's latest stream.  In short: yes, I am happy to do such a
video.  We now are on the same time zone now, which makes things
considerably easier.  In the meantime, there is no need to spam David
about it.
